Letters Patent No. 89,554, dated May 4, 1869.

ILEPROVED SNOW-PLOW.

The Schedule referred-to in these Letters Patent and making part of thesame.

To all whom it may concern Be itknown that I,- ROBERT Bnsrm,of the cityof St. John, and Province of New Brunswick, have invented a new anduseful Improvement in Snow-Plow's for railway-purposes; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to thefigures and letters marked thereon, and in which Figurel is a sideelevation of the plow.

Figure 2, a plan or top view.

Figure 3, an inside elevation.

Figure 4, the covering-board of the plow.

The same parts are indicated by the same" letters in all the figures.

. The nature of my invention consists in' a peculiar mode ofconstructing the snow-plow, and in the adaptation of its parts, so thatit may be readily put together and attached to, or taken apartandremoved from, the front of a locomotive-engine. The several partsalso being so formed that they can be. stowed in a small space in thebaggage-car when not in use, so

as to be immediately available when required, and thereby preventingdelay to trains upon the road from snow-storms.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.-

I make the side-boards A and A of plank, or other suitable materiahaboutseven and a half feet long and four and a halffeet, more orless, inwidth, and strengthen them with cross-bars, as shown in figs. 2 and 3.The frontends are mitred, so that the side-boards shall make with eachother anangle of about sixty degrees.

The mitred edges, which form the front or cuttingedge of the plow, arestrengthened and protected with plates of iron or steel, as shown infig. 1.

These side-boards are attached to the-front crossbeam B of thelocomotive, by means of rectangular holes cut through them at the rearends, to fit and rest up n the outer ends of the cross-beam, as shownbydotte lines at O, in fig. 1, or by any other convenient mode offastening; and they are further secured to the locomotive by theeye-straps D engaging with the iron pins, which are attached for thatpurpose to the posts E, depending from the front cross-beam B, as shownin fig. 3.

The front or nose of the plow is held in place by the iron brace, or rodF, which passes down from the iron cleat G, attached to the frontcross-beam B, being secured to said cleat by means of a nut and screw onthe upper end of said brace-rod, or 'bar F; and its lower end, which isformed into a hook, connects with the two books H and H, which areattached, respectively, to the side-boards A and A, thus drawing the twoside-boards closely together at the front joint or mitre, and rearwardagainst the front cross-beam B of the 10- comotive by the action of thenut and screw upon the cleat G.

The two front edges of the side-boards A and A are further secured toeach other by passing an iron rod down through the eyes of theeye-straps J, attached to the side-boards, as shown in figs. 2 and 3;or, if v spread by means of the billets M and M. which are interposedbetween the wings and the side-boards for that purpose, as shown in fig.2.

To exclude the snow from the interior of the plow, I cover it with thetop-board N, fig. 4, which may be composed of one or more pieces, andtissecnred'to its place by a rod, P, passing over it and through the eye:straps Q Q, attached to the side-boards A and- A'."

This top-board is strengthened by cross-bars or battons of wood, -asshown by dotted lines in fig. 4, the ends of which cross-bars or battenstake against the inner edges of the side-boards, which completelyprevents lateral displacement of the top-board.

a The plow herein described has been constructed and practically testedby me in clearing the track from snow, and thereby making a safe passagefor the train, when, without its timely assistance .or use, great delayand suffering would have been inflicted upon the passengers in the-trainfrom the obstruction of the track. And, from my experience with its use,I am well satisfied that were all trains supplied and fitted withthisportable snow-plow, the railway-tracks, except in extraore dinarysnow-storms, would be kept in working order,

as the frequent passage of such plows over the road would effectuallyprevent the accumulation of snow, and the consequent blockading of theroads.

The cost of this portable plow is a mere trifle compared'with itsutility, or with the cost of the ordinary snow-plows. A Its severalparts are light, and easily handled, and can be attached to thelocomotive in a few minutes, as it in nowise interferes: with thecowcatcher, or other parts of the engine, and when it is not required itcan be quickly removed, and if stowed in the baggage-car, it will occupybut little space, as all the parts will lie flat against each other.

I do not claim the snow-plow as a new invention, nor the application ofsnow-plows to locomotive-engines as my invention; nor do I claim theparticular form of snow-plow herein described; but;

What I do claim as my invention, and desire to secure by Letters Patentof the United States, is-

The snow-plow, consisting of side-boards A A, attached to the frontcross-beam B of the locomotive and to the hanging posts E E of saidcross-beam, together with the eye-straps and pins D, and brace-rod F,the whole constructed and arranged as and for the purpose substantiallyas herein described.
